" At Symantec, we take our mission to protect the world’s information very seriously. To ensure that our products are as effective as possible, we rely on Symantec experts and the security research community to watch for potential product vulnerabilities so we can act swiftly to remediate and issue product updates accordingly. As part of our standard best practices, we continually improve the protection delivered in our products through regular updates and encourage both our Norton and enterprise customers to keep their products updated to get the best protection possible.
In this case, we were alerted by a researcher on Google’s Project Zero to eight vulnerabilities he discovered after reviewing our product portfolio. Symantec has not seen evidence of any of these vulnerabilities being exploited in the wild. More importantly, fixes are currently in place and updates are now available for customers to install. While many products update themselves automatically, we encourage all of our customers to review the full list of impacted products and installation instructions, which can be found here.
Staying ahead of the threats from attackers requires vigilance and industry-wide information sharing. We remain committed to ensuring our products address today’s most sophisticated threats and we thank the security community for their assistance."
